Description :

The invention relates to a molded body for clamping outer garments, such as skirts, jackets, blazers, blouses, coats or the like, before and during a finishing treatment with a bust part and with two clamping parts that can be moved linearly towards and away from each other.

A well-known molded body of this type according to the brochure of Herbert Kannegiesser GmbH & Co. KG, 4973 Vlotho has two hem tensioners that can be moved towards and away from each other, a height-adjustable bust part and two height-adjustable sleeve tensioners on stands. An item of outer clothing to be clamped in this must be taken off its hanger, pulled over the bust part and then clamped with its hem in two opposite areas between the hem tensioners and a hem clamp each. The movement of the hem tensioners is electromagnetic, whereby the magnetic force and thus the exerted tensile forces change depending on the electrical voltage applied. The hem tensioners are therefore also subject to voltage fluctuations, e.g. in the net, whereby they move beyond the desired position when the tension is greater and thus tighten the hem of the outer garment that has been pulled over.

5 August 1991 „. .. ^St--202 3 ¹ Q/9.1:

The operating personnel can help themselves if the garments are about to spread too far apart by giving the hem tensioners a short, energetic blow with the palms of their hands on both sides, which stops them. In addition to the time-consuming handling of the garments that have to be taken off the hanger, pulled over the bust and then taken off again after finishing and pulled over the hanger again, this molded body has the disadvantage of the hem tensioners that have to be constantly monitored by the operator. The latter function electromagnetically "actively" depending on a voltage, but independently of the tear resistance of the garments to be clamped, which can therefore be exposed to the undesirable tensile or tearing stresses described above.

Based on this state of the art, the invention is based on the object of creating a molded body of the type mentioned at the beginning, which on the one hand simplifies handling, thus shortening the finishing treatment and ensuring gentle treatment of each item of outer clothing during clamping and thus during the finishing process.

This object is achieved in accordance with the invention in connection with the generic term mentioned at the beginning in that the multi-part clamping parts are connected by means of pneumatic or

5 August 1991 ,, .. ,- Sb-2023a,/9J

Hydraulic cylinders can be moved relative to one another and their clamping paths can be adjusted and controlled depending on the reaction forces of the outer garments exerted on them and consist of at least two skirt clamping parts, at least two shoulder clamping parts connected to them via a joint each, and at least one bust clamping part connected to them at the top, the external configurations of which merge continuously into one another and of which the bust clamping part and the shoulder clamping parts have a slot that is open at the top and runs parallel to the linear direction of movement of the shoulder and skirt clamping parts for the insertion of a clothes hanger. This design means that all outer garments, such as skirts, jackets, blazers, blouses, coats in the usual clothing sizes from 34 to 56, can be clamped and subjected to a finishing treatment using one and the same molded body.

However, the clamping paths of their multi-part clamping parts are adjusted or controlled depending on the reaction forces exerted on the pneumatic or hydraulic cylinders by the outer garments, which prevents excessive stress or even tearing of the outer garments.

In addition, the bust and shoulder parts are provided with an upwardly open and parallel to the linear movement direction of the

5 August 1991 .. .. .. St-2023e/9J

The molded body is provided with a slot running through the clamping parts for the insertion of a clothes hanger, so that with this molded body the outer garment does not have to be removed from the clothes hanger as in the prior art, but can be inserted together with the hanger directly into the molded body and can also be removed from it. This simplifies handling and significantly reduces the time required to clamp the outer garment into the molded body and to remove it.

According to an advantageous development of the invention, the shoulder tensioning parts engage under the underside of the bust tensioning part under the action of a spring, which is supported with one end on the skirt tensioning part that is articulated to it and with its other end against the respective shoulder tensioning part. This creates a molded body with flexible tensioning parts that can be easily adjusted to different clothing sizes, whereby in conjunction with the bust tensioning part and its continuous transition to the shoulder tensioning part, an external configuration that is very close to the human body and can be continuously changed in terms of its width is achieved.

In order to be able to easily adjust the width of the slot in the bust or shoulder straps to different coat hanger thicknesses, its width is narrowed by an elastic leaf spring.

The outer surfaces of the skirt tensioning parts and the shoulder tensioning parts are advantageously designed as partial surfaces of a circular, oval or elliptical cylinder. These outer surfaces consist of either a metallic, rust-proof perforated sheet or a perforated plastic for easy drying and disinfection and are covered with a durable textile material.

In order to be able to stretch unusual clothing sizes, e.g. in the range of 57 to 73, on one and the same molded body according to the invention, the outer surfaces of the skirt stretching parts and the shoulder stretching parts can be padded with padding pieces that are detachably connected with Velcro adhesives. These padding pieces can therefore be arranged quickly and without tools on the previously described outer surfaces and removed just as quickly.

According to a particularly advantageous development of the invention, the two skirt clamping parts and the shoulder clamping parts connected to them in an articulated manner can each be moved by a piston rod of a cylinder attached to a stationary frame and their linear movements can be synchronized by a slider-crank mechanism with a common crank attached to this frame in a pivotable manner, whereby the couplings of the slider-crank mechanisms are connected at one end to the crank and at the other end to one of the movable clamping parts, e.g. with the

5 August 1991 _it ,, »«St..2023a/9^

Skirt clamping parts are connected in an articulated manner. By coupling the two cylinders with the two synchronizing thrust-cylinder gears, a uniform linear movement of the skirt clamping parts and the shoulder clamping parts is ensured, even if the cylinders are exposed to uneven fluid.

To ensure precise linear guidance of the skirt and shoulder clamping parts and to relieve the load on the piston rods of the pneumatic or hydraulic cylinders, at least one, preferably two guide rods are arranged parallel to each cylinder in two bearings on the frame, one end of which is firmly connected to one of the movable clamping parts, e.g. the skirt clamping parts, and the other end is provided with a stop. This frame is advantageously designed as a plug-in or screw attachment for attachment to an ironing board. This means that the molded body can be used independently or retrofitted to existing ironing boards.

After another advantageous

Further developments of the invention are the cylinders with an electromagnetically controlled multi-way control valve, a
Throttle check valve and a fluid-controlled, electrical pressure switch, which interrupts the supply of fluid to the cylinders as soon as the pressure from the inner surface of the outer garments on

5 August 1991 ,, ^^ - - S t>< 2 O 2.3a/9&ldquor;t

the reaction forces exerted on the outer surfaces of the movable clamping parts reach a level preset on the throttle check valve or pressure switch. This arrangement ensures that the outer garments are gently tensioned and treated, and the supply of fluid to the clamping cylinders is immediately interrupted and the skirt and shoulder clamping parts that have been moved apart are held in this clamping position. This is the first time that a molded body has been created, in a departure from the state of the art, that is controlled "passively", i.e. depending on the individual reaction forces of the respective outer garment and not by an electrical voltage. This is associated with the incomparable advantage that, even in the case of smaller clothing sizes, these cannot be damaged by the skirt or shoulder tensioning parts, since the tensioning path of these tensioning parts is limited by the reaction forces exerted on them by the relevant outer garment and, at the slightest increase in pressure, the pressure switch interrupts the flow of fluid to the cylinders and this extended position of the piston rods is held by a holding relay to be described later.

The fluid-controlled, electrical pressure switch can be installed in the fluid line connected to the piston rod side as well as the piston side of the cylinder. In the first alternative

« * m '"> ■■■ -

the pressure switch reacts to a reduction and, in the second alternative, to an increase in pressure of the fluid on the respective piston side. The second alternative is likely to be particularly advantageous because a pressure increase is primarily noticeable on the piston side and enables a correspondingly more sensitive and faster control, whereas a drop in pressure on the piston rod side due to the outflow via the throttle valve is likely to be noticeable with a certain time delay.

The movement of the clamping parts is advantageously triggered by a separate switch for clamping and releasing, whereas the holding position of the clamping parts can be determined by the pressure switch, the set throttle check valve and a holding relay.

In order to make the bust part more flexible, it consists of a back part and a breast part, the latter of which is made up of several parts and one of its parts can also be extended and retracted under the action of another piston-cylinder unit arranged on the stationary frame. However, this tensioning path is approximately perpendicular to the tensioning path of the shoulder and skirt parts. This means that outer garments can also be tensioned on the molded body with regard to their breast area in the manner already described and can be easily removed from it after the finishing treatment.

The external configuration 2 of the molded body 1 according to Figures 1 to 3 is essentially determined by two skirt tensioning parts 3, 4, two shoulder tensioning parts 7, 8 connected to them via a joint 5, 6 each and a bust tensioning part 9 adjoining them at the top.

As can be seen in particular from Fig. 3, the bust-tensioning part 9 consists of a back part 10 and a front part 11, of which the latter 11 is made up of several parts, of which at least one part, here e.g. 12, is designed to be movable.

The shoulder clamping parts 7, 8 engage under the underside 15 of the bust clamping part 9 under the action of a spring 13, 14, which rests with one end on the skirt clamping parts 3, 4 and with its other end against the shoulder clamping parts 7, 8. The bust clamping part 9 and the shoulder clamping parts 7, 8 are provided with an upward

open and parallel to the linear movement direction according to the double arrow 16, the width of which is narrowed by one or more leaf springs 18. This allows coat hangers of different thicknesses to be clamped into the slot (17) in a force-fitting manner during the finishing process.

The skirt clamping parts 3, 4 and the shoulder clamping parts 7, 8 articulated to them are moved relative to one another by the piston rods 31, 32 of two pneumatic cylinders 19, 20 in the direction of the double arrow 16, which also represents the direction of the linear clamping path. It goes without saying that hydraulic cylinders can also be used in principle according to the invention, although pneumatic cylinders are sufficient for the low forces to be taken into account here. The movable clamping part 12 of the front part 11 of the bust part 9 is moved by a further cylinder 21 in the direction of the double arrow 22 in Fig. 3.

Shoulder clamping parts 7, 8 Partial surfaces of a circular, oval or elliptical cylinder. These outer surfaces 25, 26 consist either of a metallic, rust-proof perforated sheet or of a perforated plastic and are covered with a durable textile material. These

External surfaces 25, 26 are also advantageously equipped with Velcro fasteners 27, 28, onto which the cushioning pieces 29, 30 shown in Fig. 1 can be temporarily padded without tools and can be quickly attached and removed again, in order to be able to clamp special sizes between e.g. 56 and 73 with one and the same molded body 1.

As can also be seen from Fig. 1, the two skirt clamping parts 3, 4 and the shoulder clamping parts 7, 8 connected to them in an articulated manner can each be moved by a piston rod 31, 32 of a cylinder 19 attached to a stationary frame 33, and according to Figures 4 and 5 their linear movements along the double arrow 16 can be synchronized by a slider crank mechanism 34, 35 with a common crank 36 that is pivotally attached to this frame 33. This crank 36 is designed as a two-armed lever of equal length that can be pivoted about the pivot bearing 37 in both directions of the double arrow 38. The couplers 39, 40 of the slider crank gears 34, 35 are connected in an articulated manner at one end 41 to the crank 36 and at their other end 42 to one of the movable clamping parts 3, 4 and 7, 8 respectively. The solid lines show the retracted clamping position of the outer surfaces 25, 26 and the dotted lines show the extended clamping position.

To avoid deflections and thus to ensure trouble-free guidance of the

Piston rods 31, 32 are parallel to each cylinder 19, 20 in two bearings 43, 44 on the stationary frame 33, two each

Guide rods 45-48 are arranged so that they can be moved, one end of which is firmly connected to one of the movable clamping parts 3, 4; 7, 8 and the other end of which is provided with a stop 49. The frame 33 can be retrofitted as a plug-in or screw attachment for attachment to an existing ironing table with a steam blower device 50 and hem clamps (not shown) as shown in Fig. 6, which can be moved in the same way as the skirt and shoulder clamping parts.

As can be seen from Figures 7 and 8, the cylinders 19, 20 are provided with an electromagnetically controlled
5/2-way control valve 51, a throttle check valve 52 and a fluid-controlled electrical pressure switch 53 are connected to one another via lines 54, 55, 56, 57 to form a pneumatic circuit. In Fig. 7, the electrical pressure switch 53 is connected to the respective piston side 58 and in the embodiment of Fig. 8 to the piston rod side 59 of the cylinders 19, 20. Otherwise, the circuits in Figs. 7 and 8 are identical, so that their individual parts are also designated with the same reference numbers.

In the switching position of Figures 7 and 8, the piston side 58 of the two cylinders 19, 20 is acted upon by a fluid via the lines 55, 57. Under the effect of this actuation, the piston rods 31, 32 move apart in the direction of the double arrow 16 with the outer surfaces 25, 26 of the clamping parts 3, 4; 7, 8, whereby the outer garment 24 hanging on the coat hanger 23 is clamped according to Figure 6. At the same time, the fluid escapes from the piston rod sides of the cylinders 19, 20 via the lines 54, 56 via the throttle check valve 52. In this flow direction, the check valve 60 is closed and the fluid flow is throttled by the throttle valve 61 in accordance with the desired return flow. When the piston rods 31, 32 are extended, the

If the outer garment 24 exerts a reaction force on the outer surfaces 25, 26 and thus on the piston rods 31, 32 of the cylinders 19, 20 according to Fig. 6, the pressure of the fluid on the piston side 58 inevitably increases, whereby the coils d1 and d2 move the 5/2-way control valve 51 into a switching position in which the fluid flow to the piston side 58 of the cylinders 19, 20 is interrupted. This position corresponds to the middle position 68 of the 5/2-way control valve 51.

In Fig. 8, the pressure switch 53 is connected via the lines 54, 56 to the piston rod side 59 of the cylinders 19, 20. On this side

the pressure switch reacts to a drop in pressure when, as a result of a resistance on the outer surfaces 25, 26 as a result of the reaction forces emanating from an outer garment 24, a slowing down of the movement of the piston rods 31, 32 occurs and thus a drop in pressure occurs in the lines 54, 56.

According to Fig. 9, after switching on a main switch 62 to tighten an outer garment 24, the switch 63 can be actuated. The relay 64 thus receives the applied voltage and is activated, which initially activates the closer 65 (1.1). The coil d1 of the 5/2-way control valve 51 of Figures 7 and 8 thus receives a voltage and moves this multi-way control valve 51 into the left position shown. The piston rods 31, 32 of the cylinders 19, 20 thus extend in the manner already described to tighten an outer garment 24. In this position, the closer 66 (1.2) is actuated and the relay 64 is supplied with self-holding current as long as the pressure switch 53 remains in the closed switching position. According to Fig. 7, the pressure switch 53 is opened as soon as the pressure on the piston side 58 of the cylinders 19, 20 increases. The pressure on the piston side 58 increases when the

outer garment 24, e.g. the belt of a skirt or a hem, increasing resistance is generated, which slows down the movement of the piston rods 31. In this case, the opener 67 (1.3)

is actuated and the self-holding of the relay 64 is interrupted. The coil d1 therefore no longer receives any voltage, so that the multi-way control valve moves to its middle position 68. As a result, the piston rods 31, 32 and thus the clamping parts 3, 4; 7, 8 and 12 with their outer surfaces 25, 26 remain in the clamping position in which the pressure switch 53 has opened.

To release the outer garment 24 from the clamping position described above, the switch 69 is actuated, whereby the relay 70 receives a voltage and is activated. This actuates the closer 71 (2.1), as a result of which the coil d2 of the multi-way control valve 51 of Figures 7 and 8 receives a voltage and the 5/2-way control valve 51 is moved to the right switching position 72. This acts on the piston rod sides 59 of the cylinders 19, 20, whereby the piston rods 31, 32 move into the cylinders 19, 20 and thus the outer surfaces 25, 26 of the clamping parts 3, 4; 7, 8 move back from the outer garment 24. Then the closer 73 (2.2) is actuated and the holding relay 70 is supplied with a self-holding current. As long as the main switch 62 is closed and the switch 63 is not actuated again for tensioning, the piston rods 31 remain in this last-described, retracted position.

To tighten a newly inserted outer garment 24, the switch 63

5 August 1991 ·*.-"- ,'*.·"· St-*202=3,a/91

pressed again and the self-holding current for relay 70 is interrupted via the break contact 67 (1.3). The tensioning process can then be started again in the manner described above.

In Fig. 8, the pressure switch 53 is connected to the piston rod side 59 of the cylinders 19, 20 via the lines 54, 56. The pressure switch 53 remains closed when there is sufficient control pressure. This control pressure is achieved by sufficiently throttling the throttle valve 61. This throttling also regulates the extension speeds of the piston rods 31, 32. The stronger the throttling is set, the slower the piston rods 31, 32 can extend. As soon as the extension movement of the piston rods 31, 32 is opposed by resistance on the outer surfaces 25, 26 from the outer garment 24 to be tensioned, the throttling takes place with less effectiveness, which causes the control pressure to drop. Now the pressure switch 53 opens when the pressure drops and opens the breaker 67 (1-.3), causing the relay 64 to drop out and the power supply to the coil d1 to be interrupted. This causes the 5/2-way control valve 51 to move to its center position 68, in which it remains during the clamping process.

The pressure switch 53 is therefore opened when the pressure increases in the circuit of Fig. 7 and when the pressure decreases in the circuit of Fig. 8.

It is understood that the clamping parts 3, or 7, 8 and 9 can also be moved and used without the slot. However, such an embodiment is understood according to the principle of the invention as an inferior reproduction, since then the removal of the outer garment 24 to be clamped from the clothes hanger 23 and its subsequent re-sliding inevitably prolongs the finishing process.
